Because air motions in these clouds are driven primarily by processes tied to the presence of liquid, when water droplets competing for water vapor lose to ice crystals, an ensuing chain of events drives the cloud toward collapse.

The heat energy gained by SCW simply increases the pressure, velocity, and number of droplets, all of which then increase the heat removal.91 Significantly, the hotter SCW becomes, the more the water molecules break into ions (H + and OH --RRB- so most of the energy becomes electrical, not thermal.
